| Abstract This work was conducted to study the effect of planting methods and tillage system on some mechanization unit parameters and productivity of potato crop c.v Desiree in two different locations , Abu-Ghraib and Radwaniah . soil texture of Abu-Graib was silty clay while that of Radwaniah was clay . three types of tillage treatment were used in the experiment : moldboard plow with one way path , two-way path of moldboard perpendicular to each other ,and chisel with moldboard perpendicular on each other . Two planting methods were also used ,mechanical planting by and planting by hand . Two planting distances were used (i.e.20 and 3o cm) . Three treatments of harvesting were used including potato digger chain , potato digger frequency and hand lifting . Randomized complete block design (RCBD) was used with a split-split plot design and three replicates. A statistical analysis system (SAS) program was used on computer to data analysis to test the differences between treatments and their interactions with LSD at 0.05 level of error probability .yield parameters of potato crop were studied including germination percentage , number of tubers per plant , yield per plant and total yield (tons / dounum). The results can be summarized on the following : 1- The tillage system of plowing by chisel plow perpendicular on moldboard plow showed a significant superiorty on the other tillage system that was by increasing the mean of tubers / plant, yield /plant and total yield (ton dounum). 2- The Interaction between the mechanical planting method and the three tillage system showed a significant in crease the mean of tubers / plant and tuber weight and single plant yield compared with other treatment for both locations. 3- The interaction between the mechanical planting and the tillage system and the planting distance of 20 cm showed a significant in crease in the number of tubers/plant and the average total yield (tans/dounum) in comparison to the other treatments for both location . | ||
